VAPOR-BURNING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 607,995, dated July 26, 1898.

Application filed August 2 1, l 8 9 '7 To all whom it may concern.-

Be it known that I, ARTHUR KlTsON, a subject of the Queen of Great Britain, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Vapor-Burning Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates generally to vaporburning apparatus, and is more specifically designed to produce a lamp in which the vapor of kerosene-oil or other hydrocarbon will be used in cooperation with an incandescent mantle to produce a steady and intense light at small cost.

The preferred form of my invention is illustrated in the accompanying drawing, in which- 1 represents an ordinary burner for burning vapor mixed with air, having one or more pieces of wire-gauze 2 2 therein and suitable connections for conducting vapor and air to said burner. The cup 3 surrounds the burner and supports the globe 4., of glass, and the chimney 5 is mounted on the top of said globe.

6 is the tube from the oil-supply, which latter is under pressure either of compressed air or by reason of the elevation of the reservoir. (Not shown.) This tube passes up into the burner, preferably coincident with the axis thereof, and discharges into an uptake 7, which is surrounded by a larger and concentric tube 8, which serves as a downw take for the vapor formed by the heating of the oil in said uptake, and the enlarged'up1 per portion of the downtake, which is marked 9, serves as a reservoir for such vapor. The vapor is carried by tube 10 to nozzle 11, controlled by needle-valve 12 in the usual way, and thereby discharged into mixing-tube'li-l, which has air-inlets 1 1, controlled by the ad- '45 j ustable ring 15 in the well-known way.

16 represents an attachment to an ordinary gas-burner tip having the fine passage-Way 17 for gas discharging into the burner, and 18 18 represent air-inlets thereto with the ad- Serial No. 649,009. (No model.)

justable ring 19 for producing a Bunsen- 5o burner action.

The operation of my invention is as follows: The air-inlets 14 being closed and those 18 being open, the gas is turned on and the burner lighted. The flame thus produced quickly heats the mantle 20, mounted on said burner and supported in any suitable way, to incandescence and heats the vaporizing-tube 8 to the temperature necessary to vaporize the oil. When the needle-valve is open, the heat of said tube vaporizes the oil which has been admitted through tube 6 by opening a valve. (Not shown.) The air inlets 14 are then opened to admit air to produce a combustible mixture with the vapor. When the action of the apparatus has been thus established, the gasis shut off, the air-inlets 18 18 are closed, and the lamp continues with the oil-supply alone.

In cases where no gas 1s employed the above action of starting would be produced by means of a small-quantity of alcohol or other inflammable fluid placed in the cup 3.

In cleaning, the mantle 20, is removed, together with the globe 4:, and the downtake 8 unscrewed from its socket in the burner, after which the uptake 7 may also be unscrewed and boththe latter swabbed out in thewellknown way.

y The advantages of the construction consist in its simplicity and compactness and in the uniform vaporizing action produced by locating the reservoir of the vaporizing-tube in the center of this most intense combustion.

The reservoir 9, produced by enlarging the might be locatedwithin the mixing-tube 13 to avoid any condensing action therein; but

I have shown the outside construction as being simpler and cheaper.

The construction embodying the central vertical vaporizing-tube within the incandescent mantle also possesses special advantages with the attachment to a gas-bracket in that the weight of the lamp is materially reduced, and the center of gravity of even this light-weight structure is kept low and is nearly in a vertical line over the point of attachment to the gas-bracket. Thus the liability of the lamp to twist the supporting-bracket out of position either byits own weight or by the leverage which a side current of air would exert on the lamp structure is removed or reduced. The necessity for a reflecting-hood is also avoided, and all the upper portion of the ordinary form of vapor-burning lamp which might tend to render it top-heavy is dispensed with. The results above indicated are also assisted by the use of the short air-mixing tube attached to the base of the vapor-burner and discharging into the channel affording communication between the burner and the gas-pipe. This mixing-tube, also containingthe needle-valve, produces a compact selfcontained construction especially applicable to bracket-lam ps.

The broad feature of the construction embodying the vapor-burning apparatus mounted on a gas-bracket and provided with suitable connections for supplying gas for preliminary heating is not herein claimed, buta is shown, described, and claimed in my pending application, Serial No. 6l9,008, filed of even date herewith. Also the broad feature of the combination of the vapor-burner and incandescent mantle therefor, the vaporizing-tube with proper connections to the burner and located within the heating-zone of the burner-flame I do not herein claim, as

the details of construction Without departing from the spirit and scope of my invention so long as the relative arrangement and operation of parts herein described and illustrated are preserved.

Having therefore described my invention, What I claim as new, and desire to protect by Letters Patent, is 1 1. The combination of the supporting gasbracket, the vapor-burner and connections supported thereon, and having a connection with the interior of said gas-bracket, the incandescent mantle, and the vaporizing-tube located within the mantle and coinciding with the axis thereof, said axis being a vertical line from the point of attachment to the gasbracket substantially as described.

2. The combination of the supporting gasbracket, the vapor-burner and connections supported thereon, and having a connection with the interior of said gas-bracket, the incandescent mantle and the vaporizing-tube located Within the mantle and coinciding with the axis thereof, said axis being a vertical line from the point of attachment to the gasbracket and said vaporizing-tube having an enlargement at its upper end, substantially as described.

In testimony whereof I aflix my signature inpresence of two witnesses.

ARTHUR KITSON.
